Your disk is currently partitioned to boot in bios mode, but you booted the 16.04 installer in EFI mode. A warning message prompted you that this could be a problem and recommended performing a bios mode install instead, but you chose not to. You either need to perform the bios mode install, or partition the disk using GPT and set up an EFI system partition to install in EFI mode. This will be done for you if you choose the "use entire disk" guided install option.

Thanks for Your reply Phillip,
Yes, that helped.
Still my HP ProBook 3440s is somehow stupid, after installation without any huge warning and with grub installed my notebook still boot Windows first and I need to F9 - Boot selection during bios boot and choose ubuntu EFU loader manually.

Thats again propably error of my notebook.
